Somewhere, Earl has a log book of his trains. I have not seen it, Im sure it is in a safe that requires a finger print ID, along with a retinal scan and a DNA sample (dont ask me from where). I do know that when talking to Earl personally, he has the ability to recall events as if they happened yesterday.
I drive a CDL truck, and it is because of Earl that I keep a log book of all my deliveries; what was being transported, who it was being moved for, and what the cargo was! At first it seemed a waist of time, but since has become quite handy. My memory is not great, but it is amazing if I can remember the basics of what I did for a day, many of the smaller details come back as well...
